G-Sync not working when switching back to Windows.

It usually takes like 2-3 reboots until G-Sync gets recognized on Windows, and even then often only one of both my G-Sync monitors works. This only happens when I booted to macOS before. It's really annoying and I'm not able to find out the reason behind this bug.

Did anyone here have a similar experience?

Specs: i7 8700, GTX1080, Z370N Wifi, High Sierra
